Tried it today on a Sony and everything works just fine, it's obviously the iPhone causing all the issues (well iphone 5c and 5s atleast anyway)
you'd think the iOS platform would be a huge market share? Hopefully there addressing that issue as well as making it iPad compatible? (Steve hopefully you can update here?)
Also it maybe worth them addressing the advertising and bring specific about which iOS iphones it will work with, atleast people are clear be fore they buy it then
A curious bit was I downloaded and installed mx player on the iPhone and still no joy, just would play when it felt like it or give me black/green screens however when I tried the Sony at first it wouldn't play the video either but then I actually got an automated message come up telling me I needed to install mx player, I did this opened the video again and it played straight away, I did nothing more or different than I did with the iPhone but on the Sony it sorted it straight out
Hopefully that's my install sorted now (with exception of needing a new phone!)
Thanks for all the help everyone and I hope maybe some of the bits I experienced help someone else out on the way
(And thanks for the help from Steve - thinkware UK as well)
